Definitions

  • the invention relates to a device for uniformly metering, distributing and applying liquid-formulated protective substances, in particular pickling agents, to seeds using compressed air, with a mixing drum with a seed inlet and feed line for the protective substances.
  • the application of the mordant in a manner uniformly distributed all over the surface of the seeds is also the prerequisite for keeping the application rates as small as possible.
  • Liquid formulations of seed dressings for seeds essentially consist of a sticky carrier in which the substance which is effective for dressing is distributed.
  • Conventional spray devices are easily clogged by the carrier material required for the mordant to adhere to the surface of the seed and are therefore inoperable. They are therefore unsuitable for applying liquid mordants.
  • the aim of the invention is to provide an operationally reliable device with which all liquid formulated pickling agents can be converted into a spray mist in order to achieve an optimal all-round distribution with the lowest application rates.
  • the liquid pipeline coming from a metering pump and opening into a mixing drum and serving as a feed line for the protective substances is connected to a compensating vessel or tube for secondary air intake , and a compressed air line leading into the mixing drum is provided, in the outlet of which the outlet of the liquid pipeline is concentric and opposite the A baffle plate is arranged at the outlet of the liquid pipeline.
  • Secondary air is continuously drawn in through the compensating vessel or tube due to the negative pressure at the end of the liquid tube and mixed with the mordant; after the metering pump has been switched off, the secondary air causes the liquid pipeline to be sucked empty without dripping.
  • the secondary air empties the liquid pipe 100% without the formation of drops, which simplifies cleaning and ensures exact dosing.
  • the dosing is carried out by recording the weight of the material entering the mixing drum and inevitable impulse commands to the dosing pump. ⁇ *
  • the metering pump sucks the specified amounts of mordant liquid from a container provided with an agitator and presses it into the pipe nozzle system according to the invention.
  • compressed air - which is controlled by a pressure control manometer - a negative pressure is generated at the end of the pipe, as a result of which the liquid line is under permanent negative pressure. Due to the negative pressure generated in the liquid pipe, air is sucked in continuously through the compensating pipe built into the liquid line and mixed with the mordant liquid.
  • the distance of the baffle plate from the outlet of the liquid pipeline can be changed.
  • a cylinder body is preferably attached to the side of the baffle plate facing away from the outlet of the liquid pipe line.
  • baffle plate provided with the cylinder body fulfills the following tasks:
  • the disk diameter of the baffle disk and optionally the cylinder body determine the scattering of the spray mist generated.
  • the different amounts of dressing to be applied per kg of seed require the change in the amounts of compressed air and secondary air required for atomization by means of air pressure control.
  • the compressed air pressure is increased, the distance of the baffle plate from the end of the liquid pipe must be changed at the same time, so that a negative pressure is built up in the liquid pipe, which causes secondary air to be sucked in.
  • both the negative pressure in the liquid pipeline and the atomization angle of the spray can be regulated.
  • the shape of the spray mist can be changed from spherical to conical by baffle plates with different diameters and / or shapes and by bodies attached to the baffle plates.
  • the compressed air line is designed as an expansion cylinder immediately before its exit end.
  • the expansion cylinder is used for even pressure distribution at the outlet of the compressed air line.
  • the baffle can e.g. be held in an adjustable bracket or with a pin guided in the liquid pipeline at a distance from the outlet of the pipeline.
  • FIG. 1 shows a schematic representation of a device according to the invention
  • FIG. 2 shows the actual device for applying a pickling agent in an enlarged representation
  • FIG. 3 shows an embodiment variant.
  • - D -
  • a dosing pump 3 e.g. a membrane pump, 2 pickling agent removed from a mixer and sprayed via the liquid pipeline 4 in the mixing drum 1.
  • the seed to be treated reaches the mixing drum 1 via the inlet 11.
  • a compensating pipe 5 is connected to the liquid pipeline 4, through which secondary air can be sucked in and which also has the purpose of pressure differences in the Compensate liquid pipeline.
  • a compressed air line 10 is provided, the outlet of which concentrically surrounds the outlet 6 of the liquid pipeline 4, so that an annular gap 13 is formed for the outlet of the compressed air.
  • the compressed air line 10 is designed as an expansion cylinder 9 (see FIGS. 2 and 3).
  • a baffle plate 7 with a cylinder body 8 is arranged opposite and at a distance from the outlet 6 of the liquid pipeline 4.
  • the baffle plate 7 is held in an adjustable bracket 12 or a pin 14.
  • the cylinder body 8 has the task of determining the shape of the spray pattern.
  • the detaching edge vortices are passed on from the baffle plate 7 to the cylinder body 8, so that an elongated spray pattern is produced.
  • the length of the cylinder body 8 therefore determines the length of the spray pattern.
  • the width of the spray pattern is determined by the diameter of the baffle plate 7.
